Answer:

Step-by-step explanation:

Formula of Volume= $a^{3}$ - a = side

Therefore since the volume is given you just need to find the side.

729= $a^{3}$ = $\sqrt[3]{729}$ = a

= 9 = a

Now you know that 9 is the side, so using that find the area of one face-

Area of a square= 9 x 9 = 81 $cm^{2}$

First what you wanna do is get y by it’s self. To do that is to first add 5 on each side.

-5+3y=-4
+5 +5

3y= 1

Than you divide 3 on each side and it would give you y=1/3 if it’s a fractions problem but if you looking for decimals you would have to divide 1 by 3 which gets you .33333333.
